1 speaker system
The speaker system by one or several speakers and appropriate accessories, such as baffles, speakers, and other components of the crossover network, as a driving circuit and peripheral between the air-coupled device. Purpose is to obtain a frequency characteristic of the sound field distribution, and special sound effects desired. A typical speaker with a direct electric Speakers speaker and various combinations of electric speaker. Only the direct sound power radiated size speaker, and the sound pressure level in the service area larger unevenness. Larger acoustic power using electric horn loudspeaker can substantially obtain a sufficiently large and uniform acoustic intensity of the sound within the sound field area, but the frequency range is narrow, can not meet the requirements of high-quality music sound. Thus, the speaker often used in combination. This will not only increase the radiation wide frequency range and sound power. Application of horn speaker enclosure can be improved and the low-frequency characteristics of the speaker, directivity and efficiency; various rear speaker group, it can be further controlled acoustic power and radiation characteristics. As special sound effects, such as sound from a long distance and the case of strong noise, so to several hundred kilowatt sound power, pneumatic loudspeaker may be used at this time.
